Dear All, I just finished my second development board for the PIC32MX. The previous one used a 28-pins PIC32MX2xxFxxxB, this one use the 44-pins version PIC32MX2xxFxxxD. It is complete, with schematic, parts list, board design in Gerber and PDF formats and full source code with an RTOS and sample application. The board is single-sided and uses just two ICs, the PIC and a voltage regulator, and can be easily built by anyone with minimal SMD skills. All the tracks are 0.4mm or wider, so the board can be etched using very simple processes. It can be connected to a PC via an USB port and appears as an USB CDC device (USB to Serial converter). The USB interface is completely inside the CPU, it doesn't need an external USB interface chip.
